ChatGPT, launched in late 2022 and iterated through GPT‑4o, GPT‑4.5, GPT‑5, and GPT‑5.2/5.1 era models, has become OpenAI’s flagship application, offering a conversational interface over its frontier models. It supports text, images, code, and voice, and now powers both everyday personal use and mission‑critical business workflows. OpenAI reports hundreds of millions of weekly ChatGPT users and over 20 million paid subscribers, making it one of the fastest‑adopted software products in history. en.wikipedia.org
On the commercial side, OpenAI offers ChatGPT Plus, Pro, Business, and Enterprise plans, along with an API platform. Business and Enterprise tiers add company knowledge connectors (to tools like Slack, Google Drive, SharePoint, GitHub, Box, and more), advanced admin and compliance controls, and 24/7 support with SLAs. These plans are used by more than one million paying business customers, including large enterprises such as PwC, Accenture, Walmart, Morgan Stanley, Target, Thermo Fisher Scientific, and others across financial services, retail, healthcare, and technology. openai.com
In the content creation and AI writing market, ChatGPT competes with focused tools like Jasper, Writesonic, Copy.ai, and Grammarly Business, as well as broader AI platforms like Anthropic Claude, Google Gemini, and Microsoft Copilot. Its competitive edge lies in combining state‑of‑the‑art models (GPT‑5.x and specialized reasoning agents), a highly approachable interface, deep integrations across productivity and creative apps, and strong enterprise‑grade security and compliance. For many organizations, ChatGPT functions as a horizontal AI layer that augments knowledge workers across writing, coding, analytics, research, and customer engagement.
